A Model Context Protocol (MCP) server that provides real-time cryptocurrency data and analysis through CoinCap's API. Features include price
MCP Crypto Price MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. A Model Context Protocol (MCP) server that provides real-time cryptocurrency data and analysis through CoinCap's API. Features include price tracking, market analysis, and historical trends.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Once MCP Crypto Price is connected, these are the calls the assistant has available:
MacOS — ~/Library/Application Support/Claude/claude_desktop_config.jsonWindows — %APPDATA%/Claude/claude_desktop_config.jsonSTDIO — via the COINCAP_API_KEY environment variable (see Usage examples above)You will need 2 environment variables: COINCAP_API_KEY, SMITHERY_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
COINCAP_API_KEYPlenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP Crypto Price's toolset — MacOS, Windows, STDIO — is a fair guide to whether it matches your workflow. It is maintained by truss44; worth a glance at recent repository activity before you build anything load-bearing on it.
